Title: Researchers Develop Simple Method for Light Control Based on Direction
Post by: rdunk on March 28, 2014, 07:29:21 PM
(Because this is light-science related, there may be a better forum board for this OP"

In reading through this article about new findings related to the control of "light', my thought is "this could potentially have direct application to light-related areas of photography, and in the related studies of what is or is not seen in photographs. Could this such impact/improve even the deuem process??

WASHINGTON, March 27 (Xinhua) --

"Researchers from the United States and China said Thursday they have developed a simple method for filtering light waves based on direction, a finding that could ultimately lead to advances in solar photovoltaics, detectors for telescopes and microscopes, and privacy filters for display screens.

Light waves can be defined by three fundamental characteristics: their color, or wavelength, polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive.

In a paper published in the U.S. journal Science, researchers at the Massachusetts Institute of Technology (MIT) and Zhejiang University, however, reported a system that allows light of any color to pass through only if it is coming from one specific angle while reflecting all light coming from other directions.

The researchers said they "are excited" because it represents " a very fundamental building block" in the efforts to control light.

The new findings could have great applications in energy, and especially in solar thermophotovoltaics, by ways of selectively controlling light reflections to improve its efficiency, Shen said".
